Hi gang:
This post is related to the zip lat/long request I recently made and
received such an overwhelming response -- many thanks to all.
In any event, let's say we have a end-user who is looking for
services within his zip-code AND we have a dB of service providers
who are willing to render service within a set distance (like 50
miles) from their location.
Now, it's a simple matter to convert the user's zip code to lat/longs
and then find out how many service providers there are within their
area and then show that list to the end-user. That's not the problem.
The problem is, could you guarantee to a "preferred" service provider
that they would receive top-listing 25 percent of the time? Keep in
mind that preferred service providers will overlap. So, the question
is how to accommodate for that overlap?
If anyone has an algorithm, I would be interested in hearing it.
Cheers,
tedd
